Deduction withou permission

I called A & G a few weeks ago and asked them to cancel my policy and that I'll join again when they are financially better.

The person I spoke to suggested that I rather place my policy on hold and ONLY when I call to reinstate my policy will premiums be deducted from my bank account.

Last week a premium was deducted from my account without my calling to give permission for this to happen.

I sent an email on Monday to complain, but haven't received any response.

Very disappointed with the service.
